I'm trying to open the driver display panel in Control Panel, and this error message keeps appearing.
The full error is:
[code]The NVIDIA Display Control Panel extention cannot be created.
Possible reasons include:
Version mismatch. Reinstalling drivers may solve the problem.[/code]

I already reinstalled the latest driver 5 times, and it still happens.
My graphics card is GeForce 8800GTX, and my OS is Windows XP Professional x64 Edition.

I have same problem - just downloaded latest driver for Geforce 8600M GT and now the control panel throws that error: "the Nvidia control panel extension cannot be created". I've rebooted but still no luck.

None of you have stated what drivers you are running or the OS you are running them on. Any of you tried different drivers? Remembering to uninstall the drivers completely before trying new drviers? Running a driver cleaner between installs?

How did you manage to SLI those 2 cards?

regarding the 9300+8400, seems like that the 9300 is an onboard graphics, perhaps he's running hybrid SLI between those two gpus, perhaps try to disable the onboard gpu then try to run the 8400 w/o sli.

to the OP: perhaps the driver you've installed isn't for XP64bit? and yeah, like Hexen said. run driver sweeper after you've uninstalled your current driver and before you install new driver.

there's a guide for reinstalling graphics driver the proper way on my sig :)

I'm OK again - I think it was an error thrown by trying to use a shortcut to the old control panel. In any case I did a reinstall of the latest drivers and then went directly to the control panel by right clicking on the desktop display.

I have the exact same problem (GPU: GeForce 8800GTX)...
I tried reinstalling the latest 186.18 drivers for Vista (32bit) but it still gives me the same error.
Now all I can think of is Nvidia's latest drivers (June '09) being faulty for the 8800GTX. My Control Panel works fine when I roll back my drivers.

WAY TO GO NVIDIA!!!

M currently downloading new drivers (190 just came out today... hope they work for me...)

Well buddy... if you're asking me not to blame nVidia... you should elaborate a bit more as to why I shouldn't do that! As a matter of fact, try to google this error... there are hundreds and thousands of posts of the same kind which are about the previous two faulty driver versions released by nVidia for 7, 8,9 & 200 series.
nVidia isn't concerned about the previous cards I guess. My 8800GTX was released around 25-30 months ago and it's already extinct (Only that particular card in the 8 series)!
It cost me a f@#king bomb because I chose to buy it right after it was released... (Oh well... I love this card though... its quite powerful)

And when it comes to maintaining and performing a computer update... I know how to maintain my PC dude... I know what it needs to make it run efficiently!

For ppl who were unable to open the nVidia Control Panel... the new drivers (190.38 for Vista 32 bit) solved my problems. I guess nVidia realized their blunder and released a new set of drivers as soon as they could. I hope this update works for the others too.
